IMPROVEMENT INl JOURNAL-BOXES.

'.lhe Schedule referred to in' these Letters Patent and making part of the same I, ELIZA DEXTER MUREEY, of New York, count-y of New York, State of New York, have invented an Improved Journal-Box, of which vthe following is a specification.

Nature and Object of the Incei'z'tt'on.

Myimproved journal-box and bearing consist of a hollow block of wood, lined with the Vmaterial patp ented to me on the 12th day of July, 1870, or the equivalentof such material, and otherwise constructed, as fully described hereafter, the whole forming a box and bearing which is cheaper,v more durable, and less liable to become `heated than the usual metal boxes -with metal bearings.

Description ofthe Accompanying rwing.

.Figure 1 is an external view of my4 improved journal-box;

Figure 2, a plan. view; and

Figure 3, a sectional view ofl'the box, with portion of a spindle or shaft, which turns in the box.-

A General Description, The journal-boxesof the spindles of a spinning-ma,-

' chine, and of other light shafts, are generally of br'ass extent; they consume a large quantity of oil,.and

sometimes occasion excessive friction, causing the heating of both bearing and journals. e

I have found that a vbox consisting of wood, and.

containing a lining of non-metallic absorbent material impregnated with lubricant, will not become heated, or

cause the heating of the journal. l It is much cheaperthanone of metal, equally eflicient, and more durable; and that the composition with which the lining' is impregnated, being partiy absorbed by the wood,4

causes the lining to adherefirmly to the box.

The box may be ot' any suitable shape, externally, adapted to the situation which it is to occupy; preierably, it is a cylinder, A, bored, to admit the detachable non-metallic bearing x, through which the spindle X passes, and provided, at its upper andllower ends, with annular ribs or projections, c e.

'Ihe bear-ing may be made from the material patented to me on vthe 12th day of July, 1870, or of equivalent material, and bent to a tubular form, to fit the box, the lower end of the papel' tube being expanded to form a flange, which is confined to the rlb c byaring, n, as shown in g, 3, that portion of the tube which is folded over the lower edge of the rib forming a bearing for the shoulder y of the spindle,

To the top of the box is fitted `a cap, d, and the ring e accurately fits, without bearing against the en# largement of the spindle, the access of dust to the bearing being thus prevented;

I claim as a new manufact-uref# A journal-box and bearing, consisting of a hollow blockof wood, containingalining, x, of material, substantially as described, and adapted to a journal, as setforth.

.In testimony whereof, I have signed my naine to this specification in the presence of twosubscribmg witnesses.
